This is just it, if I do a SIP trace, on what is happening, the 
registrations are bouncing between the 2 addresses, and the inbound call 
comes in from the last address that my registration was against.

What appears to be happening though is that my peer definition's DNS 
address does not get updated with the last address registered against. 
For example:

[a] register against example.com's IP
[b] sip peer [example] has resolved the host=example.com to be
[c] call comes in from registered address, this works fine
[d] i then re/refresh-register against
[e] sip peer [example] still has the initial resolution of 
host=example.com to be
[f] call comes in via and this fails at my pbx.

Can you recall what the issue may have been?

No problem, thanks for the info/pointers thus far.
